Thanks Sir. This lecture helps me in preparing interviews for Mechanical Design . We know that material selection is one of the important step in Mechanical design of any component and through this video i got all concepts in very organized manner.
Great work!🤩✅ Expecting more sessions like this from you sir!🦋 Mechanical design - how to make a component from Design to fabrication- if you make a video about it(including everything) that's will be fabulous💕
I think that we may not use this method for bolts because the weight saving is not much. This is because the weight % of bolt compared with the total structural weight of the plane wing is not much. Moreover, with bolts (nut and rivet) we need to have extra safety which can only be provided by the right kind of bolt material such as high strength steel. Corrosion prevention of the bolt, nut and the rivet is also very important.
@@ensarcetin2491 However, you can do the analysis by treating bolt only in tension. This is geometrically very simple, you can compare with specific strength values between different suitable materials. Corrosion and creep properties are also very important during materials selection for bolt material. Toughness is another important one because fracture can happen by fatigue.
The second value of C that's go up i choice it or there's calculation? Second question He gives some materials density and young mud to put in performance index law or he wouldn't? In exam
Do you mean C in Equation 5.14? Yes, you can choose it based on your design requirements. Just the way you would select strength of a material based on design and application. Density and modulus has to be known to find performance index.
For bolt you may not go for light weight because strength is very critical including creep. The weight of the bolt compared to the total structure may not be too high. However, you can do the analysis by treating bolt only in tension. This is geometrically very simple, you can compare with specific strength values between different suitable materials. Corrosion and creep properties are also very important during materials selection for bolt material.
C is actually design specified parameter depending upon how good you was the performance. Higher C will give better performance of the materials but also at a higher cost. So, the designer has to optimized performance with cost.
Thanks for asking. Prof. M F Ashby has written many books in which he has explained these topics. You can also find in one of the chapters of my book. The link will be given in the top description. Please let me know if you are able to download or not.
Yes, I took a delight in watching this video. The more tutors like you, sir, the easier life for students. Thank you
Many thanks indeed!👍
This is super effective. I have really learnt something new today. Thanks so much sir for this tutorial!
Sir truly your way of explaining things are very easy to understand, thank you sir.
Thanks Sir.

Good Job! Junior Mech Eng student in my first Machine Design class. This helps a lot
👍
Great class, simple, explanative and understandable. Congrats.
Glad you liked it! I appreciate.👍
Really nice vedio for all students who interested in design field thank u sir.. await for next vedio..
Very informative understandable ....need more videos like this from u sir
Thank you sir, what i am looking for Now I got it,
Awesome Explanation 👌 🎉❤
Great Video. Thanks for uploading it. You are putting really useful knowledge in the world. Looking forward to learning more from you.
Thanks a lot for the comment. 👍
Very informative 🎉🎉 thanks
Thanks Sir, Superb work
How do we plot the equation on Asbhy charts? I didn't understand that part clearly! Can you explain in detail?
Excellent video! Very clear explanations.
Thank you!👍
Very good lecture. Thanks
👍

wow high density of information
👍
Thanks, it was really great 🤩🤩
Thankyou sir
Great Info!!
Thanks!👍
is the equation 5.1 at minute 8:36 is work only for cantilever beams ? or for general use ?
It is for cantilever only. For other configurations you can look up the equations in a textbook.
ı try to find material index for bolts on plane wings.Can ı use strong and light material index?

Thank you! Very useful, I was wondering do you have strategies on materials selection of a multi-materials component? Thank you!
Thanks for asking. Could you mention what component you have in mind?
Hello, I tried to find material index for bolt on aircraft wings but I could not find it can you help me please?

I'm still confused how to get the value of c to determine the y-axis
C is actually design specified parameter depending upon how good you was the performance. Higher C will give better performance of the materials but also at a higher cost. So, the designer has to optimized performance with cost.
@@engineeringmaterials-tribo5142 okay, thanks for the explanation. It really helped me.
Hello,
Is the slope of ASHBY's curve always 2?
No. It changes according to the geometry you are dealing with.
@@engineeringmaterials-tribo5142 Ok, thank you for your clarification.
Thank you sir.
can u please suggest us some good book for this topic?
